SXDOOL EC Motor Cooling Fan, 120mm Fan, 120mm 38mm AC 110V 115V 120V 220V 240V, Dual Ball Bearing 3000RPM Powerful

Cooling Solution Speialist EC is Electronically Commutated, inpute voltage is AC 115V 120V 220V,but the motor runs on the DC Voltageif speed is slightly increased or decreased, output and energy usage will remain relatively linear. A similar AC fan in that environment would either drastically drop airflow output or drastically increase energy usage.EC motors can also have windings made in both directions that would allow the reversal of polarity to reverse blade spin direction; this is a feature that not all EC have. Energy Saving Higher Airflow than Normal AC Fan Simple connection
